MAINTENANCE ITEMS
PROPELLERS
Propeller blades should be removed when making a change to the configuration
of the ALTA 8 to prevent propeller strikes in the event of unintentional motor starts
and should be replaced on an as needed basis if they become damaged. Generally, a
nick on the leading edge that is large enough to catch a fingernail indicates that the
prop should be replaced. If the blade composite structure becomes delaminated, the
propeller blade should be replaced.
Freefly makes folding propeller assemblies available that include the blades and
prop hub fully assembled. They are available in clockwise and counterclockwise
orientations.
CAUTION
Only use propellers supplied by Freefly on ALTA 8. Use of third-party
propellers can cause motor instability, overheating and failure.
